4. A 2.00 C charged 1.00 g cork ball is suspended vertically on a 0.500 m long light string in the presence of a uniform downward-directed electric field of magnitude E-1.00x105 N/C. If the ball is displaced slightly from the vertical, it oscillates like a simple pendulum. (a) Determine the period of the ball's oscillation. (b) Should gravity be included in the calculation for part (a)? Explain. (15) 3. The magnetic field shown in Figure 4 directed into the paper....
